Optics and photonics. Lasers and laser-related equipment. Test methods for the spectral characteristics of lasers1 Scope This International Standard specifies methods by which the spectral characteristics such as wavelength, bandwidth, spectral distribution and wavelength stability of a laser beam can be measured. This International Standard is applicable to both continuous wave (cw) and pulsed laser beams. The dependence of the spectral characteristics of a laser on its operating conditions may also be important.

Risk reduction (protective) measures related to the operations carried out by the machine are specified in machine specific standards
